如果你想要修改ProgressBar的foreground 颜色，用下面的方法是不行的： ProgressBarIsIndeterminate= True Foreground= Aquamarine / 要修改ProgressBar的颜色，需要override默认主题资源字典中的如下值： ResourceDictionary.ThemeDictionaries ResourceDictionaryx:Key= Default x: String x:Key= ProgressBarIndetermin

　　

　　如果你想要修改ProgressBar的foreground 颜色，用下面的方法是不行的：

<ProgressBar IsIndeterminate="True" Foreground="Aquamarine" />

　　要修改ProgressBar的颜色，需要override默认主题资源字典中的如下值：

<ResourceDictionary.ThemeDictionaries>

<ResourceDictionary x:Key="Default">

<x:String x:Key="ProgressBarIndeterminateForegroundThemeBrush">Red</x:String>

</ResourceDictionary>

</ResourceDictionary.ThemeDictionaries>

　　可以将这个override添加到App.xaml中，或者创建一个新的资源字典，并合并到App.xaml中：

　　A、直接添加到App.xaml中，如下代码：

<Application.Resources>

<ResourceDictionary>

<ResourceDictionary.ThemeDictionaries>

<ResourceDictionary x:Key="Default">

<x:String x:Key="ProgressBarIndeterminateForegroundThemeBrush">Red</x:String>

</ResourceDictionary>

</ResourceDictionary.ThemeDictionaries>

<ResourceDictionary.MergedDictionaries>

<!--

Styles that define common aspects of the platform look and feel

Required by Visual Studio project and item templates

-->

<ResourceDictionary Source="Common/StandardStyles.xaml"/>

</ResourceDictionary.MergedDictionaries>

</ResourceDictionary>

</Application.Resources>

　　B、创建了一个CustomStyles.xaml，并将该文件合并到App.xaml中：

<Application

x:Class="Sample.App"

xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">



<Application.Resources>

<ResourceDictionary>

<ResourceDictionary.MergedDictionaries>

<ResourceDictionary Source="Common/StandardStyles.xaml" />

<ResourceDictionary Source="Common/CustomStyles.xaml" />

</ResourceDictionary.MergedDictionaries>

</ResourceDictionary>

</Application.Resources>

</Application>

　　CustomStyles.xaml:

<ResourceDictionary

xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">

<!-- Global Overrides -->

<ResourceDictionary.ThemeDictionaries>

<ResourceDictionary x:Key="Default">

<x:String x:Key="ProgressBarIndeterminateForegroundThemeBrush">Red</x:String>

</ResourceDictionary>

</ResourceDictionary.ThemeDictionaries>

</ResourceDictionary>
